Extreme Arctic melting has a new suspect: The same powerful gases screwing over the ozone

Half of Arctic climate change between 1955 and 2005 may be attributed to ozone-depleting substances banned in 1987 by the Montreal Protocol.

And then scientists figured out these substances ripped a hole…

The Arctic Is Undergoing Changes Scientists ‘Never Expected Would Happen This Soon’

Photo: GettySurprise, surprise: The Arctic didn’t do too well this past year. You can thank global warming for that.The National Oceanic and Atmospheric Administration released its annual Arctic Report Card Tuesday, and the findings show a region in the midst of a rapid transformation. Wildlife populations are decreasing, sea ice is melting, and the Arctic…

Arctic Shifts to Carbon Source – Stunning Reversal After Capturing Carbon for Tens of Thousands of Years

The Active Sensing of Carbon Emissions over Nights, Days and Seasons (ASCENDS) campaign flew over Nome, Alaska, on August 5, 2017, as part of NASA’s Arctic Boreal Vulnerability Experiment (ABoVE). Credit: NASA A NASA-funded study suggests winter carbon emissions in the Arctic may be adding more carbon into the atmosphere each year than is taken…

To stop Arctic ice melt, Ice911 proposes scattering tiny, glass beads

Scientists have discovered that melting in Greenland and Antarctica is occurring much faster than they previously thought. This year, the extent of Arctic sea ice was the second-lowest ever recorded.Polar ice melt contributes to sea-level rise and also leads the planet to heat up faster, since ice reflects sunlight back into space.An organization called Ice911…

Arctic sea ice plunges to dismal levels

Sea ice in the Canadian Arctic Archipelago. Image: AP / Shutterstock By Mark Kaufman2019-09-23 21:02:25 UTC After a year of extreme melt, Arctic sea ice ended up dropping to its second-lowest level on record — a mark only surpassed by melting in 2012. The National Snow and Ice Data Center (NSIDC) announced Monday that the…
